Stewart Pharmaceuticals
• The Stewart Pharmaceuticals Corporation is considering
investing in developing a drug that cures the common cold.
• A corporate planning group, including representatives from
production, marketing, and engineering, has recommended
that the firm go ahead with the test and development phase.
• This preliminary phase will last one year and cost $1 billion.
Furthermore, the group believes that there is a 60% chance
that tests will prove successful.
• If the initial tests are successful, Stewart Pharmaceuticals can
go ahead with full-scale production. This investment phase
will cost $1.6 billion. Production will occur over the next 4
years.

Stewart Pharmaceutical: Decision to Test
• Let’s move back to the first stage, where the decision boils
down to the simple question: should we invest?
• The expected payoff evaluated at date 1 is:

So we should test.

8.4 Options
• One of the fundamental insights of modern finance
theory is that options have value.
• The phrase “We are out of options” is surely a sign
of trouble.
• Because corporations make decisions in a dynamic
environment, they have options that should be
considered in project valuation.

Options
• The Option to Expand
– Has value if demand turns out to be higher than
expected.
• The Option to Abandon
– Has value if demand turns out to be lower than
expected.
• The Option to Delay
– Has value if the underlying variables are
changing with a favorable trend.

8-9
The Option to Expand
• Imagine a start-up firm, Campusteria, Inc. which
plans to open private (for-profit) dining clubs on
college campuses.
• The test market will be your campus, and if the
concept proves successful, expansion will follow
nationwide.
• Nationwide expansion, if it occurs, will occur in
year four.
• The start-up cost of the test dining club is only
$30,000 (this covers leaseholder improvements and
other expenses for a vacant restaurant near campus).

We plan to sell 25 meal
plans at $200 per
month with a 12-month
contract.
Variable costs are
projected to be
$3,500 per month.
Fixed costs (the lease
payment) are
projected to be
$1,500 per month.
We can depreciate

improvements.

The Option to Expand: Valuing a Start-Up
• Note that while the Campusteria test site has a
negative NPV, we are close to our break-even level
of sales.
• If we expand, we project opening 20 Campusterias
in year four.
• The value of the project is in the option to expand.
• If we hit it big, we will be in a position to score
large.
• We won’t know if we don’t try.

Discounted Cash Flows and Options
• We can calculate the market value of a project as the
sum of the NPV of the project without options and
the value of the managerial options implicit in the
project.
M = NPV + Opt
 A good example would be comparing the
desirability of a specialized machine versus a more
versatile machine. If they both cost about the same
and last the same amount of time the more
versatile machine is more valuable because it
comes with options.

The Option to Abandon: Example
• Suppose that we are drilling an oil well. The drilling
rig costs $300 today and in one year the well is
either a success or a failure.
• The outcomes are equally likely. The discount rate
is 10%.
• The PV of the successful payoff at time one is $575.
• The PV of the unsuccessful payoff at time one is $0.

The Option to Abandon: Example
Traditional NPV analysis would indicate rejection of the project.
Expected = Prob. × Successful + Prob. × Failure
Payoff
Success Payoff
Failure Payoff
Expected
= (0.50×$575) + (0.50×$0) = $287.50

The Option to Abandon: Example
Traditional NPV analysis overlooks the option to abandon.
Success: PV = $575
Sit on rig; stare
at empty hole:
PV = $0.
Drill
 $300
Failure
Do not
drill
NPV  $0
Sell the rig;
salvage value
= $250
The firm has two decisions to make: drill or not, abandon or stay.

The Option to Abandon: Example
• When we include the value of the option to abandon, the
drilling project should proceed:
Expected = Prob. × Successful + Prob. × Failure
Payoff
Success Payoff
Failure Payoff
Expected
= (0.50×$575) + (0.50×$250) = $412.50

Valuation of the Option to Abandon
• Recall that we can calculate the market value of a
project as the sum of the NPV of the project without
options and the value of the managerial options
implicit in the project.
M = NPV + Opt
$75.00 = –$38.61 + Opt
$75.00 + $38.61 = Opt
Opt = $113.64

• Consider the above project, which can be undertaken in any
of the next 4 years. The discount rate is 10 percent. The
present value of the benefits at the time the project is
launched remain constant at $25,000, but since costs are
declining the NPV at the time of launch steadily rises.
• The best time to launch the project is in year 2—this
schedule yields the highest NPV when judged today.
